9 Claims.

This invention relates to lagging for reels used for storing andtransporting heavy material, such as lead covered cable, and moreparticularly to lagging provided with means for securing the laggingupon such reels.

Although not limited thereto, the present invention is particularlyapplicable to the securing of a series of sheet metal lags ofsubstantially channel-like cross-section placed side by side across theouter peripheries or rims of metal reel heads to form a completeenclosure for the cable storage space of the reel, and particularly toreels wherein the outer edges of the rims are appreciably inside the endfaces of the remaining portion of the reel heads. The rim engaging endportions of the spaced arms of the channel lags are preferably narrowedor reduced in depth by notching the bottom end corners of the armswhereby in addition to appreciably strengthening the lags against impactstresses longitudinal movement of the lags on the reel is efiectivelyprevented. The rim engaging end portions of the lags are reinforced byinserting and welding within each end portion of the lag a filler orliner in the form of a short channel member provided with an outer endwall.

An object of the present invention is the provision of an improved reellag and simple secur} ing means therefor, whereby lagging may be readilyand effectively secured to reels and easily removed therefrom.

In accordance with theabove object, the invention contemplates in oneembodiment thereof, as applied to reels and lagging of the abovementioned types, lags each having at one end a portion adapted to behooked over the outer edge of one head rim, the opposite end of the laghaving a portion extending over the outer edge of the other head rim andterminating in an outturned flange. Encircling the lag flanges are aplurality of arcuate lag retaining metal strips, each strip beingassociated with a predetermined number of lags with opposite ends of thestrips bolted to elements fixed to the head behind the ends of thestrips.

In accordance with another embodiment of this invention the lags aresimilar to the lags described hereinbefore except that the portion atone end thereof which terminates in an outturned flange is formed toterminate in an outturned hook, the series of hooks being encircled by alag securing wire rope or band which is first secured at one end to oneof a plurality of predeterminedly spaced knobbed studs projectingangularly from the end surface of the reel head A.

and then entered into a number of the hooks on the lags, comprising agroup, and thereafter around another stud and thence over anothergroupof hooks, the rope being applied under tension at each group, andthus continuing around the head until the entire series of lag hookshave been encircled by the rope, and finally securing the free endthereof to the first stud.

Other objects and advantages of this invention will more fully appearfrom the following detailed description, taken in conjunction with theaccompanying drawings, wherein Fig. 1 is a view in side elevation of ametal cable reel provided with the improved lagging and means forsecuring the lagging to the reel embodying the invention;

Fig. 8 is a detail section through one of the knobbed studs of theembodiment shown in Fig. 5.

Referring now to the drawings, a preferred form of lagging embodying theinvention is illustrated, for example, in conjunction with a cable reelcomprising a pair of spaced heads l0, interconnected by a drumv II forholding a lead covered cable '52, or other heavy material that may bewound thereon. The cable reel itself may be of any suitableconstruction, although a welded all-metal construction is preferred. Inthe construction illustrated, the heads each comprise an inner annularchannel member I3, an outer annular rim l t concentric therewith,channel spokes l5 extending between the inner annular member and the rimand welded thereto, and an annular metallic disc or head sheet l6 weldedto the spokes on the side facing the drum.

The spokes are notched at their inner ends, as shown in Fig. 2, toreceive the ends of the drum and outwardly turned inner flanges ll ofthe head sheets, which, together with the drum, may

be welded to the annular channel l3. In the construction illustrated,the spokes I are also notched at their outer ends to receive outwardlyturned outer flanges M of the head sheets, which may be welded to theunder Side of the rims I4. The outer ends of the channel spokes l5, itwill be noted, arenarrower than the inner ends thereof and thus the sideflanges are inclined inwardly from the annular channel member I3 to therim I4. This arrangement, wherein the outer edges of the rims areappreciably inside the end faces of the remaining portion of the reelheads, per-.- rnits the reel to be laid on its end face with the rim andthe spokes and the lags, to be presently described, spaced from theground or other support for the reel.

The preferred form of lagging embodying the invention comprises aplurality of lags 25 of uniform size and construction and suflicient innumber so that when placed side by side on. the rims I4 and lengthwiseacross the width of the reel, as shown in Figs. 1 and 2, a completecovering or enclosure is provided for the cable storage space of thereel. The lags are preferably of channel-like cross-section and formedfrom sheet metal. Each lag comprises a substantially flat web portion 25and integral depending side arms or flanges 21, 2'! on opposite sidesthereof. .As best shown in Fig. 3, the flanges 21 are slightly flaredoutwardly and at their bottom edges they are formed with outwardlyextending open beads to provide rigidity and are slightly resilient totransverse pressure, so that when a series of the lags are laid in placeside by side on the rims of a reel and pressed together, the abuttedhead portions form a tight seal between the lags.

The lags 25 are placed on the reel so that the bottom edges of theflanges 21 thereof contact the rims I4, as shown in Figs. 2 and 3. Therim engaging end portions of the lag flanges 2'! are preferably narrowedor reduced in depth by notching the bottom end corners of the flanges,as indicated at 29 (Figs. 2 and 3). The resistance of the lags to impactstresses is thereby increased. Also, the notched corners permit theremaining unnotched portions of the lag flanges to project inwardlybetween the reel heads and thereby serve as braces therebetween as wellas effectively preventing substantial longitudinal movement of the lagson the reel. To further increase the strength of the lags 25 and theirresistance to impact stresses the rim engaging end portions of the lagsare reinforced by increasing the wall thickness thereof by inserting andwelding within the end portions a filler 30 in the form of'a shortmetallic channel member of a cross-section substantially conforming tothe cross-section of the notched end portions of the lags. Eachreinforcing channel member 30 comprises a web portion 3| and a pair ofdepending side arms or flanges 32, 32, which at their bottom edges areflush with the bottom edges of the notched end portion of the lagflanges which contact the rims I l. channel fits snugly within thenotched end portions of the lags, where they may be secured, forexample, by spot welding, as indicated at 33 (Fig. 2).

Each of the reinforcing channels 39 is formed with a vertical outer endwall portion 34, preferably formed integral with the web portion 3| anddepending therefrom (Figs. 2 and 3). The vertical wall 34 serves as aclosure for preventing cinders, stones, etc., from entering the cablestorage space of the reel through the otherwise open ends of the lags.In order that the lag The dimensions are such that the reinforcingflanges may not be restrained from spreading slightly when underpressure so as to distribute the load over a plurality of lags, thevertical wall portion 34 of the reinforcing channel 30 is preferably notsecured to the lag flanges 27 along their adjoining edges. Also, asshown in Figs. 2 and 3, the height of the end wall 34 is slightly lessthan the flanges 32 of the channel so that sufficient clearance isprovided between the rims I4 of the reel heads and the bottom edge ofthe end Wall to permit a free spreading movement of the lag flanges 21.

One embodiment of the improved means for securing the lagging of theabove described type to the reel head rims I4 comprises the following.Referring particularly to Figs. 1 to 3, inclusive, the web portion 26 ofeach of the lags 25 at its left end (Fig. 2) is provided with anintegral arm 3! extending inwardly over the end wall 34 of the filler 3Band the outer edge of the associated head rim I 4 and terminating in anout-turned flange or lip 38. Encircling the lag lips 38 are a pluralityof arcuate shaped lag retaining metal strips 39, which in the presentembodiment comprise four strips, each strip retaining a predeterminednumber of lags on the reel head. Each strip at one end is struckoutwardly from the plane of the strip a distance substantially equal tothe thickness of the metal, as indicated at 40, and opposite ends of thestrips which overlap (Fig. 3) are provided with slots4l. A similar slotis formed in each of the lag arms 31 adjacent the 1ip38 thereof. In thepresent embodiment, four of the spokes I5 of the left reel head (Fig. 2)have welded thereto a plate 45 which spans the inner surfaces of theside flanges of the spoke at their outer edges immediately below the rimI4. The particular spokes which carry the plates 45 are spaced 90 apartcorresponding to the points of overlapping of the retaining strips 39.Each of the plates 45 is provided with an aperture for receiving a bolt4'! which in securing the lags to the reel head is passed behind theplate 45 and then through the aperture thereof and the'slots of the lagarm 31 and overlapping strips 39, respectively.

Each of the lags 25 at their opposite ends is formed with a hook shapedarm 50, which like the arm 3'! is formed integral with the web portion25 and extends inwardly over the end wall 34 of the filler 30 and theouter edge of the associated head rim I4 and terminates in a right angleportion which hooks under the rim as shown in Fig. 2.

To secure the lags 25 to the head rims I4 the reel is preferably mountedon a suitable device whereby it may be freely rotated during thesecuring of the lags. The first lag 25 is fixed to the pair of head ribsI4 by hooking the arm 55 thereof over the right rim I4 (Fig. 2) andaligning the slot M in the arm 31 at the opposite end with the apertureof one of the spoke plates 45 and then inserting the bolt 41 through thealigned aperture and slot. Successive lags 25 are then mounted on therims I4 side by side to cover one quarter of the rim peripheries andanother bolt 4'! is then inserted through the aligned aperture of thespoke plate 45 and slot of the lag arm 31, which spoke plate and lag armare spaced 90 from the first spoke plate, and lag arm, respectively.Thereafter, a retaining strip 39 is mounted in position outside of theseries of lag lips 38 with the bolts 41 extending through the slots atopposite ends of the strip.

It will be apparent that the lags 25 between the first and last one ofeach group, which are bolted to the spokes l5, will be retained inposition on the reel heads by the out-turned lips 38 of the arms 31integral with the lags. The positioning of successive groups of lags 25and their retaining strips 39 is continued around the heads until theentire rim peripheries have been covered, thereby completely enclosingthe cable storage space of the reel. Nuts are then threaded onto theouter ends of the bolts 4! and this completes the effective securing ofthe lags to the reel. The removal of the lags from the reel it will beobvious may be easily effected.

' Referring now to Figs. 5, 6 and '7 which illustrate an alternativeembodiment of the improved reel lag and securing'means therefor, lags 5!similar to the lags 25, previously described, are employed, except thatthe arm 31 thereof which terminates in an out-turned lip 38, is formedto terminate in an out-turned hook 52 (Fig. 5). The reel head with Whichthe lag hook 52 is associated is equipped with a plurality of spacedlmobbed studs 53 which project angularly from the reel head intermediatethe inner channel member l3 and the rim M. The studs 53 in theparticular reel structure illustrated are suitably secured in and weldedto the web portions of certain of the spokes l5 spaced, for instance, 45apart so that a group of lags are positioned on the rim it between eachpair of studs. Each of the studs inside the head thereof may be providedwith a tapered peripheral slot 54 (Fig. 3) in its periphery into which awire band or rope 55 may be wedged. I

To secure the lags 5! to the head rims it the reel may be mounted in themanner described in connection with the previously described embodimentand the end of the wire rope 55 is then secured to one of the studs 53by tying it to and wedging it into the tapered slot thereof. A pluralityof lags 5i comprising a group, are mounted side by side on the rims l4,in the manner described hereinbefore, to cover one-eighth of the rimperipheries, the first lag being positioned adjacent the stud to whichthe end of the wire rope is secured. The wire rope is then entered intothe successive hooks 52 of the group of lags, drawn tightly around thefollowing stud and wedged into the slot thereof, and thereafter enteredinto the hooks of the following group of lags mounted in position, drawntightly around and wedged into the slot of the next stud and thuscontinuing around the head, the rope being applied under tension at eachgroup of lags, until the entire series of hooks 52 have been encircledby the single rope, and finally tying the free end thereof to the firststud. The cable storage space of the reel is now completely enclosed bya plurality of groups of lags each group being individually retained inposition on the peripheries of the rims M in an effective manner. Anexpeditious removal of the lags from the reel may be effected by merelyreversing the above described operations of securing the lags inposition.

In Fig. 7 is shown another embodiment of lagging which may be similar tothe lagging described hereinbefore, except that the side arms or flanges21 thereof are designed to interlock as indicated at to. This iseffected by providing one of the flanges 21 at its bottom edge with anopen bead 8!, which preferably may be less open than the beads indicatedon the lagging hereinbefore described, for freely receiving the oppositeflange 2? of the adjacent lag which is a plain flange without a bead atits lower edge. To further increase the strength of the channel typelags and their resistance to impact stresses, particularly intermediatetheir reinforced ends, the web portion 26 of the lag may be formed witha longitudinally extending reinforcing embossment or rib 62. Either typeof lagging may be used on the reel and either one may be secured theretoby one or the other of the described embodiments of securing means.

The above described types of lagging and the several embodiments ofmeans for securing the lagging upon reel heads permits the lags to bereadily and effectively secured to the reel and easily removedtherefrom; Furthermore, due to the particular arrangement of the laggingand securing means upon the reel, the reelafter being lagged may be laidon either of its endfaces or rolled during handling with other reelswithout damage to the securing means.

Although in the described embodiments of lag securing means the hookedshaped arm 50 is disclosed for securing one end of the lags to the reelrim, it is to be understood that both ends of the lags may be secured inposition by being equipped with one or the other of the securing meansassociated with the other ends of the lags.

It is to be understood that the invention is not limited to the specificembodiments thereof herein illustrated and described except insofar asis defined by the appended claims.
